commission a large angel statue for my tombstone, keep it in my yard until I need it

My grandparents on my mothers side have those flat plaques that the cemetary people can mow over. That just doesn’t do it for me. I’ve spent bajillions of hours in cemetaries oogling the statuary and photographing the angels. Why aren’t there any new ones? I don’t want to be remembered by having my photo sandblasted into shiny granite. And its an expensive purchase….I don’t want wait until I’m dead to get it either.
